Cell organelles

Plasma membrane

the membrane found in all cells that separates the interior of the cell from the outside environment.

Nucleus

Controls the normal activities of the cell Contain the DNA

Nuclear membrane

A double layer that encloses the cell's nucleus, where the chromosomes reside.

nucleolus

An area inside the nucleus of a cell that is made up of RNA and proteins and is where ribosomes are made.

chromatin

a mixture of DNA and proteins that form the chromosomes found in the cells of humans and other higher organisms.

ribosomes

the cellular machinery responsible for making proteins.

rough endoplasmic reticulum

a cellular organelle composed of many folds of tissues and channels.

smooth endoplasmic reticulum

an organelle found in both animal cells and plant cells.

Golgi apparatus

A stack of small flat sacs formed by membranes inside the cell's cytoplasm

Vacuoles

a membrane-bound cell organelle.

Lysosomes

a membrane-bound cell organelle that contains digestive enzymes.

mitochondria

membrane-bound cell organelles

cytoskeleton

a network of protein filaments and tubules that provides structural support and shape to the cell.

microtubules

that are part of the cytoskeleton, aiding in cell shape, transport, and division.

microfilaments

thin protein fibers that are part of the cytoskeleton, involved in cell movement and shape.

cytoplasm

the gel-like substance within the cell membrane that contains organelles and is the site of many cellular processes.

centrioles

cylindrical structures involved in cell division, facilitating the organization of microtubules.

cilia

hair-like structures that extend from the surface of many eukaryotic cells, aiding in movement and sensory functions.

flagella

long, whip-like structures that enable cell movement and are found in some prokaryotic and eukaryotic cells.

central vacuole

A large, membrane-bound organelle found in plant cells that stores nutrients, waste products, and helps maintain turgor pressure.

chloroplast

An organelle found in plant cells and some algae that conducts photosynthesis, converting sunlight into chemical energy.

cell wall

A rigid outer layer found in plant cells, fungi, and some prokaryotes that provides structural support and protection.
